The endoscopic pipeline inspection is also called QV inspection, a method of detecting the inside of the pipeline using endoscopic technology. Using this detection method can not only solve the problem that the camera distance cannot meet the length of the channel and the upload rate is too slow to be synchronized but also can accurately determine the material defects, corrosion degree, and specific location of the pipeline, and the detection results can be used as the basis for evaluating the health of the channel.
- The principle of pipeline endoscopy detection technology
Use video to monitor and shoot the internal deposition of the pipeline, pipeline damage, foreign matter penetration, leakage, branch pipe concealed connection, etc., and can see and record all the conditions inside the channel from a long distance. Then the video is transmitted to the ground and stored in the host computer. Professionals analyze all the video data one by one, systematically and comprehensively understand the basic situation of the pipeline, understand its drainage quality and operation, as well as the location of the water outlet and the degree of damage to the channel, write a pipeline inspection report, and provide for the track. Maintenance and Restoration offer an economical and efficient detection method.
The QV detection system comprises the central controller, the portable pole with the camera installed, and the cable to connect the central controller and the mobile bar. The main controller can be tied to the operator’s chest with a strap, and the operator can adjust the free rotation of the camera, lens stretching, shooting, and observation by changing the central controller and saving the original video data in the main controller. For further analysis.
- Pipeline endoscopy inspection technology working procedures
The QV technical work program testing work program includes: collecting existing pipeline information, work plan design, on-site exploration, internal industry data analysis, and writing reports. According to the actual situation, adjustments can be made. In some cases, such as when the well is full of water, it is necessary to adjust the valve to lower the water level to less than half of the nozzle to advance the QV.
- Video Analysis Method of Pipeline Endoscope Inspection Technology
The critical work of QV technology is to interpret and analyze the video data to see whether there are defects in the pipeline, the type, level, and several flaws.
The emergence of pipeline endoscopic detection technology provides a simple, intuitive, and effective detection method for the status quo of the urban pipeline network system, ensuring the stable operation and development of the city. Pipeline endoscopic inspection technology plays a huge role in urban pipe network inspection and has apparent application effects in other fields such as electric power, petrochemical, aerospace, and other areas.
- How does an industrial pipeline endoscope solve the problem of pipeline bends?
Pipeline, everyone must be familiar with it. Pipes of different materials and shapes are used in all aspects of industrial production and serve thousands of households. The pipeline may seem ordinary, but it has a vital role! Is there any foreign matter inside the pipe? Are the pipe-to-pipe connections secure? Are the pipes corroded? These problems are widespread. So how can we quickly find the answer and plan for the next step? Let’s talk about it today!
How to survey the situation inside the pipeline has always been a headache. Are there foreign objects inside? Is the internal welding secure? These questions, industrial endoscopes, can quickly give answers! The inner wall of the pipeline is easy to produce scale and other foreign matter. Once the foreign value is generated, it will not only affect the regular use of the channel, but in severe cases, it may cause an explosion.
Let’s examine how the industrial endoscope picks up internal foreign matter. The pipeline’s internal Corrosion and the weld seam also need attention.
Now industrial endoscopes can see not only foreign objects clearly but also measure various values of foreign objects! Sections of pipe elbows have always been difficult to inspect.
Using endoscopy inspection solutions:
1. Quick, easy, and complete coverage
2. Covering an extensive range of pipe diameters
3. Cover the elbow surface
4. Fast, easy, and complete coverage
5. Reduce duplication of labor and inspection time
6. Larger sound beam coverage width can ensure fast detection
Corrosion in pipelines is complex. Not only to find them in time but also to analyze them properly, which caused the decline. Metal corrosion can be quickly investigated on-site through industrial endoscopes, and corrosion composition information can be obtained promptly, which helps to understand Corrosion and find solutions to prevent decay. It has broad application prospects in refineries, petroleum and petrochemical industries, power plants, and shipbuilding industries.
